3402 Wisdom, provisional designation 1981 PB, is a stony

rotation period of 4.99 hours.[4] It was named after American planetary scientist Jack Wisdom.[2]

Orbit and classification

Wisdom is a

semi-major axis of 2.13 AU). Its orbit has an eccentricity of 0.28 and an inclination of 5° with respect to the ecliptic.[1]

The body's observation arc begins with a precovery taken at Palomar Observatory in February 1977, more than 4 years prior to its official discovery observation at Anderson Mesa.[3]

Physical characteristics

Wisdom is an assumed stony S-type asteroid.[4]

Rotation period

In October 2006, two rotational

U=3/3).[7][a]
A high brightness amplitude typically indicate that the body has an elongated rather than spherical shape.

Diameter and albedo

According to the survey carried out by the

albedo of 0.32 and 0.283, respectively.[5][6] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and derives a diameter of 2.59 kilometers based on an absolute magnitude of 15.34.[4]

With a

mean diameter of approximately 2.5 kilometers, Wisdom is one of the smaller mid-sized Mars-crossing asteroids. It is assumed that there are up to 10 thousand Mars-crossers larger than 1 kilometer.[10] The largest members of this dynamical group are 132 Aethra, 323 Brucia, 2204 Lyyli and 512 Taurinensis
, which measure between 43 and 25 kilometers in diameter.
